23   Since June 18, 2013 dilbert.com strips are not accessible anymore
24   directly from the RSS feed, this message is displayed instead:
25
26     Dilbert readers - Please visit Dilbert.com to read this feature. Due
27     to changes with our feeds, we are now making this RSS feed a link to
28     Dilbert.com.
29
30   How unhandy is that, was it because of a management decision?
31   Maybe a parody dilbert strip is needed about this issue...
